IMPROVEMENT, -|N CULTIVATORS.

Specification forming part of Letters Patent No. 184,042, dated November7, 1876; application filed I v March 8, 1876. V

To all whom it may concern:

Be it known that I, ALMON HUNT, of Macomb, county of McDonoughjand Stateof Illinois', havejinvented certain Improvements in Cultivators; and Ihereby declare thefollow' ing to be a full, clear, and exact descriptionof the construction and operation of the same, reference being had tothe accompanying drawing, making part of this specification, and inwhich- Figure 1 is a perspective view of a cultivator embodying myinvention. Fig. 2 is a rear elevation of the axle, and sectional viewthrough the axle-section-conneoting sleeve, and through the sleevesto-which the plowbeams are coupled. Fig. 3 isa side elevationnear wheelremoved.

This invention relates to improvements in that class .of cultivatorsknown as tongueless cultivators and the invention consists, first, inmounting upon the axle a plate, to which a forwardly-projectingsupportingpole for the axle may be attached, for sustaining the axle inan elevated position when the plows are hooked up thereon fortransportation upon their own wheels; second, in con structing saidplate with stops, and in so attaching the supporting-pole thereto as tolimit the inclination of the axle from a vertical position, when therear ends of the plowbeams are elevated thereon; third, inconstrnctingaforesaid plate in theform of a sleeve, with its ends soconstructed that they will act as stops to limit the oscillations of theaxlesectious in relation to each other, and the consequent relativeadvanced and receded positions of the plows, each to the other.

Referring to the parts by letters, A represents the axle, made in twosections, A A, each section crank-shaped, and formed of an upper part orjournal, a, an elevating or side part, a, and a horizontal part, a. Thesupporting-wheels B are journaled on the outer ends of the parts a, andsleeves O are also journaled on the parts a, between the wheels B andthe angle from which springs the side a. The sleeves C have series ofprojecting lugs c, to which the-ordinary cultivator-plows D are attachedby their beam-plates d, as plainly shown in the drawings. E E are thedraft-bars, each having its forward end formed I into a hook, -e, forthe attachment of the single-tree, an d the connection thereto of thedraft animal, and'itsrear end bifurcated and journaled, an arm at eachend of a sleeve,0,and on the part a of the axle. F is a link, its lowerend'pivoted to the draft-bar E, and its upper end slotted, as shown inthe drawings. f 'is a'guide-bolt projecting from-the part a of the axle,through the-slotted links E, and provided with a head on its outer end.G is a tubular sleeve, receiving the ends a of the axle, and provided ateach end with downwardly enlarged and projecting plates 9 in closeproximity to the parts a of the axle on their inner sides. to each plateg by means of studs h, of such length as to bring the plates 9 H snug tothe sides of the arm a, but still to allow it to slide between them, andof such distance apart as to act as stops to limit the inclination ofthe axle when the plows are suspended thereon, and to properly limit theadvance of each plow relatively to its fellow. I is a supporting-pole,and has two braces, t, pivoted at one of their ends to near its rearend, and their other ends formed into hooks t". J is a loop or eyeattached to one side of the sleeve-coupling G, and perforated to receivean eyebolt, j.

The pole I may be readily put in place by inserting its rear end in theeye J and inserting the eyeboltj, and engaging the hooks t" in holes 9in the plates g, and may be as readily and easily removed.

K K are studs projecting from the plates G, and over which the hooks L,attached to the plow-beams, may be hooked to suspend the plows.

In operation in the field the pole I is removed, and the draft-animalsattached to the draft-bars E. As either animal advances ahead of itsfellow the wheels B are retained in the line of progression by means ofthe sections A of the axle oscillating in the sleevecoupling G andchanging positions, as shown at Fig. 3, where the near section A isshown with its attached plow advanced, and the other section receded,and the extent of movement of this kind is also. shown, the stops hstriking the arms a, and thereby limiting the His a plate, connected onesame. The slotted-arms or braces F, it will be seenfrom Fig; 3, allowthe draft-plates E to retain their position wliile'the vertical angle ofthe sides a of the axle are changing, and while the positions of thearms a are fixed they allow the forward ends of the draft-plates E to beraised or lowered in the obvious manner, and the rear ends of the slotsstriking the bolts f will retain the bars E from dropping much below ahorizontal position.

The lateral and vertical --movements of the rear ends of the plow-beams,independently of each other, are obtained in a usual manner bymovement-on the lugs 0, and movement of the, sleeves O on the axle a,respectively.

For the purpose of transporting the machine on its own wheels B, thesupporting-pole l is put in place, and by means of an ordinary neck-yokeconnected to the necks of the draftanimals. The rear ends of the plowsbeing then elevated, the hooks L may be hooked over the studs K, andboth sections A A of the axle will assume the position shown by the nearsection at Fig. 3, at whichposition,

the stops h engage the arms a of the axle, and limit further movementwithout raising the forward end of the pole I. When the set forth.

2. The sleeve G, having plate 9 H on its ends, and stops it operating,in combination with the detachable pole I, axleA, and plows D, havinghooks L for engaging studs K, substantially as and for the purposespecified.

3. The sleeve G, having plates g H, and

stops h between the plates, operating incombination with thesectionsA Aof a divided axle to hold them in place and limit theirmotion,substantially as and for thepurpose specified.

ALMON- HUNT.
